Jim Dockendorff of MadisonSensor explains what to look for when selecting liquid level sensors and flow detection solutions.

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...

Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

State energy codes in the United States, which must be at least as stringent as the ASHRAE/IES 90.1-1999 standard, require automatic shutoff of lighting in commercial buildings greater than 5,000 ...

You’re probably familiar with those regular old light switches that you fumble for in the dark, but maybe you’re unclear on what a smart switch is. Good news: you’ve come to the right place. A smart ...
